One kind clears off brush filament and preparation method thereof
Technical field
Field is cleared off the present invention relates to ceramic product, brush filament and preparation method thereof is cleared off more particularly to one kind.
Background technology
Processing is cleared off for 3D ceramic products in the industry at present, is mainly carried out with hairbrush collocation Liquid diamond/diamond cream.And hair
Brush material mostly selects pig hair or other animal wools.Because animal wool has the limitation such as limited source, price height, quick abrasion, therefore
The serious cost for constraining batch machining reduces and efficiency improves.And Chinese patent application 201510937642.9 discloses one kind
The polish brush and polishing method of PBT materials, because PBT materials have good water imbibition, most of polishing fluid can be adsorbed
In hairbrush, so as to reach the effect for reducing polishing fluid dosage.But PBT material hardness is low, wear resistance is poor, therefore efficiency be present
The defects of low, quick abrasion, surface quality difference.
The content of the invention
It is a primary object of the present invention to overcome the deficiencies in the prior art, there is provided a kind of service life is long, it is good to clear off quality,
Efficiency high, process costs it is low clear off brush filament, and preparation method thereof.
To achieve the above object, the present invention uses following technical scheme:
One kind clears off brush filament, including brush body and brush filament, and the material of the brush filament contains following components by weight:
Further:
The grinding-material contains one or more of in carborundum, aluminum oxide, diamond, boron nitride, corundum.
The grinding-material is diadust, and particle diameter is at 0.5~5 μm.
The lubricant includes the one or more in stearic acid, stearic amide, oleamide.
The compatilizer is that maleic anhydride is grafted compatilizer, it is highly preferred that the mass fraction of compatilizer is 2~8 parts.
The glass fibre is alkali-free glass fibre, and filament diameter is 5~25 μm.
The length of the brush filament is 20~30mm, a diameter of 0.05~0.5mm of the brush filament, it is highly preferred that 0.05~
0.2mm。
A kind of preparation method for clearing off brush filament, made using the above-mentioned formula for clearing off brush filament.
Further:
The preparation method comprises the following steps:
Step 1: pressing the recipe configuration each component, and wherein PA6 and PA612 nylon resin materials are dried, cut
Piece processing;
Step 2: each component is well mixed;
Step 3: the material after will be well mixed is added in extruder, mixing extrusion is carried out.
Step 4: the mixed material after extrusion is cooled down;
Step 5: using hauling machine, traction wire drawing is carried out to the mixed material after cooling;
Step 6: brush filament is cut into predetermined length.
The preparation method meets the one or more in following process conditions:
Drying nylon resin materials in step 1 causes its moisture content to be less than 0.05% weight;
It is 10~20min that the time is mixed in step 2;
Maximum extrusion temperature >=280 DEG C in step 3;
A diameter of 0.05~0.5mm of wire drawing in step 5;
20~30mm length is cut into step 6.
The invention has the advantages that:
It is provided by the invention to clear off brush filament, brush filament material selection PA6 and PA612 nylon resin mixed grinding materials such as Buddha's warrior attendant
The compositions such as stone powder are made according to the special formulation of the present invention, clear off that the quality that brush filament clears off is high, and efficiency high is wear-resistant using this
Property it is strong, service life length, recycle the cycle can reach more than 72H.The 3D curved surfaces of ceramic material are cleared off, processing effect is equal
It is even, steady quality.Lapping liquid can be particularly well adsorbed in brush filament and product surface during clearing off, and processing stability is high, processing
Surface quality is good, is also effectively saved lapping liquid.Brush filament is cleared off using the present invention to carry out sweeping method, is cleared off efficiency high, is cleared off yield
More than 90.0% can be reached, and lapping liquid dosage can be reduced, significantly reduce production cost.
